Here is a debug patch that should apply against either 2.6.31 or 2.6.33.
To apply it, you'll need the Ubuntu sources or sources from kernel.org
To apply them, just use
$ patch -p1 < patchfile
Then rebuild the kernel or just the sctp module if you don't want to wait too
long. To build the module you do
$ make net/sctp/sctp.ko
Thanks for doing this.
